Abstract
The utility model relates to a bolt which consists of a bolt base, a bayonet lock and a handle; wherein, the bolt base is arranged in the middle part of a fixing door leaf of a double-leaf metal door and is provided with a long hole. The bolt is characterized in that upper and lower bolt guide plates are arranged at the back of the bolt base; the handle passes through the long hole arranged on the bolt base from the front of the bolt base and connects the bayonet lock arranged at the back of the bolt base; and the connecting point of the handle and the bayonet lock is arranged between two bolt guide plates; the bayonet lock passes through two guide holes of two bolt guide plates. Compared with the prior bolt, the bolt provided by the utility model has the advantages that the bolt has compact structure and small size, thereby reducing the damage to the strength of the door leaf, caused by the door leaf punching during installing the bolt; besides, the stroke of the bolt is long, the head of the bolt is far away form a bolt panel, so the strength of the door leaf can not be affected.
Description
Technical field
The utility model belongs to a kind of accessory of metal door, is a kind of latch of metal door specifically.
Background technology
At present on the fixedly door leaf of products such as all biparting steel entering house doors, anti-theft safety door, steel timber, be provided with a latch, its latch has turnover plate type, button driving, sawtooth slidingtype etc., the fork of above-mentioned latch is all nearer apart from the latch panel, latch installing hole on the door leaf is near excessively apart from the door leaf end, causes the door leaf strength reduction; Latch is in stroke, and bolt rod can depart from the bolt rod axle slightly, has influence on the location dimension of door leaf doorframe pin hole to a certain extent; The latch panel length about 180, when being installed on the door leaf, causes the door leaf strength reduction usually.
Summary of the invention
The purpose of this utility model provides that a kind of latch panel size is little, the latch stroke is long, the fork latch all far away apart from the latch panel, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of plug housing, bayonet lock and handle, wherein plug housing is arranged on the fixedly door leaf middle part of biparting metal door, plug housing is provided with a slotted hole, be characterized in: the back side of plug housing is provided with two latch guide plates up and down, the slotted hole that handle passes from the front of plug housing on the plug housing is connected with the bayonet lock that is arranged on the plug housing back side, the tie point of handle and bayonet lock is between two latch guide plates, and bayonet lock passes the pilot hole of two latch guide plates.
The middle part of above-mentioned plug housing is a plane that concaves, and slotted hole is arranged on this plane.
Above-mentioned bayonet lock is provided with a hole, and the inside end of handle inserts in the hole on the bayonet lock, realizes being connected of handle and bayonet lock.
At least be provided with the hole face of two circles on the slotted hole on the above-mentioned plug housing.
Above-mentioned handle constitutes by three sections, one section lever piece that is a size greater than slotted hole outside plug housing; One section in slotted hole is an oval-shaped glissile segment of myopia, and its oval-shaped major diameter size is greater than the width of slotted hole, and less than the diameter of circular port face on the slotted hole, oval-shaped minor axis size is less than the width of slotted hole; The 3rd section is the linkage section that inserts bayonet lock.
The utility model is compared with existing latch has following characteristics: compact overall structure, size are less, have reduced when latch is installed the door leaf punching to the destruction of door leaf intensity; The latch stroke is long, and fork is far away apart from the latch panel, and door leaf intensity is not had influence.
